physical modeling for study of deep foundations can be performed in simple chambers (1g), calibration chambers (cc), and centrifuge apparatus (ng). these common apparatus face certain limitations and difficulties. recently, frustum confining vessels (fcv) have been evolved for physical modeling of deep foundations and penetrometers. shaped as the frustum of a cone, this device applies steady pr...

Oxidative stress has emerged as a key component of many diseases that affect the vasculature. Oxidative stress is characterized as a cellular environment where the generation of oxidant molecules overwhelms endogenous anti-oxidant defense mechanisms. NADPH oxidases are a family of enzymes whose primary purpose is generation of reactive oxygen species (oxidant molecules) and therefore are likely...

AIMS To identify the types of interventions that are effective in reducing stress in student nurses, and to make recommendations for future research. BACKGROUND Student nurses experience significant stress during their training and this may contribute to sickness, absence and attrition. Given the global shortage of nurses and high dropout rates amongst trainees, the importance for developing ...

background: life style is the collection of behaviors influenced by individuals' characteristics, social interactions and socio-economic situations. since, pregnancy is a part of life it can change persons' life style. this study has tried to evaluate the relationship between life style and some characteristics of pregnant women. methods: this study was an analytic cross sectional study. the da...

conclusions it seems that implementation of an appropriate interventional program related to adaptive ways of coping in order to deal with stress is effective in mental health and quality of life promotion. results the most and the least used ways in coping with stress were planful problem solving and confronting coping. considering the quality of life, the most and the least scores were relate...

It has long been recognized that simultaneous exposure to heat stress and oxidative stress shows a synergistic interaction that reduces organismal fitness, but relatively little is known about the mechanisms underlying this interaction. We investigated the role of molecular stress responses in driving this synergistic interaction using the nematode Caenorhabditis elegans To induce oxidative str...
